In recent years, research on the noncontact conveyance system with the application of electromagnetic levitation technology has been active. However, because of the high nonlinearity of the attractive force of an electromagnet and various uncertainties in circuit current such as changes in resistance attributable to heat generation by the electromagnet, the stability of levitation is not sufficiently ensured. In addition, for an actual steel plate conveyance process, it will be necessary to develop a control system that takes into consideration various parameter errors, such as the nonuniformity of plate thickness and the associated weight variation. In this study, we examine the possible achievement of the robustness of the effect of the characteristics of electromagnetic variation induced by heat generation using μ-synthesis.
